Based on the occurrence frequency of wave‐like structures in 23,691 individual measurements of thermospheric density, we demonstrate that there is no significant hemispherical correlation between satellite‐measured thermospheric wave‐like structures and the tropospheric vorticity area index in the epoch 1974‐1976. However, in the northern polar zone, (60°‐90°) N, wave occurrence frequency is greater for large values of the 500 mb vorticity area index.
